The study of market equilibria is central to economic theory and traces back to 1874 with the seminal work of Walras [1]}. In his work, Walras investigated the problem of setting prices and determining an allocation of goods to agents such that the market clears, i.e., all goods are sold and each agent receives its most favoured bundle of goods that is affordable. The existence of such a market equilibrium was established in the work of Arrow and Debreu [2]} under mild conditions on the utility functions of buyers. A special case of Walras' model was independently proposed by Fisher in which consumers spend their budget of money (or artificial currency) to buy goods that maximize their utilities, while producers sell capacity constrained goods in exchange for currency [3]}.
